gas 体辅助 injection molding parts molding tool has injection pressure low, products warpage deformation small, surface quality good and easy processing thick relatively large products and other advantages, in recent years development very fast. it in 发达国家 used for 商业化 plastics products production more already has 20 more year. gas 体辅助 injection molding parts molding plastics melt injection and gas 体（ generally using/adopting nitrogen gas ） injection molding parts molding separation. and injection molding parts molding process versus ratio, gas 体辅助 injection molding parts molding has more more process parameters need and control, for/regarding products design, injection molding parts mold design and molding process control has requirements. gas 体辅助 injection molding parts molding process is toward mold cavity inner resin material injection, rear high pressure pressure shrink nitrogen gas 导入熔 melt material material in, gas retardant force most small direction toward products low pressure and high temperature 区域. gas in products in flow 时, it through 置换熔 melt material material 而掏空 thick 壁截面. this 置换出 material material products its separation. filling process formed rear, gas 体继续 provide holding pressure pressure, will injection shot product shrinkage or warpage issues drop most low. gas 体辅助 injection molding parts molding advantages: low injection pressure make residual stress reduce, from make warpage deformation drop to most low; low injection pressure make clamping force requirements reduce, can use small machine 台; low residual stress improve/increase products dimensions and stability property; low injection pressure can decrease/reduce or remove products flash 出现; formed product thick separation is in 空, from decrease/reduce plastics, most more can 达40％; and products versus ratio molding cycle shrink short, also to foaming molding semi; gas 体辅助 injection molding parts molding make structure property and design degree large improve/increase; for 一 壁 thick relatively large products through gas technology can one-time molding; reduce mold cavity inner pressure, make injection molding parts mold loss consumption decrease/reduce, improve/increase its as lifespan; decrease/reduce 射入点, gas can hot runner system from make injection molding parts mold cost reduce; sheet/plate and 凸起根部 gas 体通道 increase rigid degree, 不必考虑 shrink issues; good surface light degree, use 担心会像 foaming molding belt/tape phenomenon. use gas 体辅助 injection molding parts molding technology rear design will product design more add complex, injection molding parts mold manufacturing can 够简化 injection molding parts mold structure. products function increase and products parts decrease/reduce make production cycle shrink short, must assembly and rear 期修整工 as. in molding CD pallet and machine electronics in pressure sheet/plate production in table/sheet gas 体辅助 injection molding parts molding can used for thin products production manufacturing. dimensional stability improve/increase, products residual stress decrease/reduce and warpage amount reduce is gas 体辅助 injection molding parts molding technology main/primary advantages. gas 体辅助 injection molding parts molding technology application will 变 越 越 complex more 样. in, can use gas 体辅助 injection molding parts molding technology production quality from 30g～18kg products.
